"The versions of Oracle Siebel CRM installed on the remote host are affected by multiple vulnerabilities as referenced in
the January 2026 CPU advisory.

  - Vulnerability in the Siebel CRM Deployment product of Oracle Siebel CRM (component: Application Interface
    (JDOM)). Supported versions that are affected are 17.0-25.11. Easily exploitable vulnerability allows
    unauthenticated attacker with network access via HTTP to compromise Siebel CRM Deployment. Successful
    attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable
    crash (complete DOS) of Siebel CRM Deployment. (CVE-2018-1000632, CVE-2020-10683, CVE-2021-33813)

  - Vulnerability in the Siebel CRM Deployment product of Oracle Siebel CRM (component: Server Infrastructure
    (OpenSSL)). Supported versions that are affected are 17.0-25.11. Easily exploitable vulnerability allows
    unauthenticated attacker with network access via HTTPS to compromise Siebel CRM Deployment. Successful
    attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Siebel
    CRM Deployment accessible data and unauthorized ability to cause a partial denial of service (partial DOS)
    of Siebel CRM Deployment. (CVE-2025-4575)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
